# How to calculate the relative deviation ?

You will need:
• calculator
• program Excel
# 1

In order to calculate the relative difference between the two measures is necessary to share more for less.The resulting number is then to be multiplied by a hundred, and a hundred and subtract.For example, yesterday there were 5 of sweets, and today 4. In order to know the relative deviation between the day is necessary ((5/4) * 100) -100 = 25%, that is, the relative deviation of these two days of 25%.Now that you know how to calculate the relative deviation.

absolute deviation is the difference between reporting and the base period for calculating it is necessary to subtract from the larger less.For example yesterday there were 10 of tangerines, and today 7. To calculate the absolute deviation must be 10-7 = 3, that is, the absolute deviation of 3 mandarin.Now I understand how to calculate the absolute deviation.

In order to calculate the percent deviation of the actual figure must be multiplied by one hundred and divided ta

rget figure.After that you need from the resulting figures take a hundred.If the numbers turn out negative, it means that much interest does not fulfill the plan, if positive, the plan was exceeded.Here's how to calculate the percentage deviation.

To calculate the average deviation is necessary in the Excel document in a row to put all these numbers, then select the aggregate function "VARP" and click "OK".The function should be specified number mesh ranging tables which are for calculating the deviation value.Then from the resulting number is necessary to extract the square root.The resulting number is the average deviation.Now I understand how to calculate the average deviation.

Standard deviation is a volatility indicator from the old descriptive statistics.It is a very popular measure of dispersion used in descriptive statistics.And as close to the technical analysis of the statistics, you can use this value in the technical analysis to determine the degree of scattering instrument values ​​over time.In this article you will learn how to calculate the standard deviation in Excel.In this analysis, the standard deviation is called an indicator of volatility, while it does not change its meaning.In order to calculate the standard deviation in Excel has a feature that bears the name of STDEV.This function is divided by the standard deviation for the total population (STDEV. D) and standard deviation of the sample (STDEV. B).the desired band and press the "OK" must be selected for the calculation of the standard deviation.
